Applicativi filed July 20, 1918.- Serial No. 719,552.

To all whom t may concern.'

Be it known that l,- Eowlr S'IORY, a citizen of the United States, residing at North Grafton, in the county of Worcester and Stateof Massachusetts, have invented new and useful Improvements in Folding Cases, of which the following is a specification.

The object of the present invention is to provide a folding ease comprising two mem bers adaptedto telescope one into the other 'thereby forming n mmpletely closed box,

` The structure may he built of paper or other light material and so arranged that il; can be, shipped in knockdown eondition sind 'subsequently assembled for' use,

More pnrtieulsrly the inversion aims no provide s structure wherein the inner receptaule is locked against accidentel removal, this locking being egt-acted throo h the medimm of a llexiblehaindie carrie ner receptacle andy pretending through the housing member. A tongueonthe housing member cooperates' with this' handle lin lm iting enxwlse movement of the inner receptacle. End flops nre provided on the inner receptacle to prevent 'spilling of its contents after 4such endwise movement as is permitted before the longue eomes into engagement with the handle to' form the looking means. The inner and outer membersjmsy each be constructed of 'si' single peper blankl so arranged that; it een be flattened ont whenv not in' use.l

Figure 1 is a perspective View of tlecon plete case in condition for use.v llig.l 2 is n perspective vview of the inner sect-ions' moved .outwardly as far as the handle lbeik will permit, a portion of the housing "rirmber l being broke/n away to disclose the structure -with1rn v'Figs-.il is. arldetail of the-hsgndle lock/'illustrating .the inode of unlocking, Fig. 4 is a plan offs fragment of the fiat blank out o f which the housing member muy be constructed, illustrating the irregular out lwhereby vthe locking tongue is formed. Fig.

5 is a perspective View showing the inner -member partly folded up.4

The folding onse of the present invention comprises'an outer or housing member 1 and an inner or containing receptacle 2. T/he housing member 1 may be constructed ,of paper or of liber, leather or the like in a single thickness or reinforced by a plurality of thicknesses as desired and is shaped on the inf up out of s rectangular blank with overlap ping ends at the botto-ni 3. This overlapping gives stiffness and rigidity to the' bottom and is of value when the cose is of lare size such for instance as might be used .or lnnndiry boxes, suit enses and the like. At the center of the blank out; o which the housing member is formed is s U-shaped cut 4 of substantial width which leaves B; tongue 5 attached integral' -to the sheet and serviceable :le rl lock for the handle of lthe case as hereinafter explained. The illnf member or receptacle may also be formed of a sin Vle sheet of paper or other suitable mjteria reinforced orv not, as desired, the blank being out to liorln n side wall o, a, top wall 7, a. bottom wall 7', end walls 8 and 9' with 7 Y extensions lo anni 11,` and sonst-le wings 12 for engagement with slots 13 in the top and bottom walls to lnclr the end' Walls inpo'siA tion. Figt 5' shows the' end Wall 8 folded upsnd 'end wall 9 in position reidy for folding'. The end extensions I0 and 11 have the functions of stilfenln the ends 'of the receptacle lo giverigfdn-y o the' entire otros ture and to prevent collapse,- of the top and bottom walls or c rnshlng at the 'eorners o the ease. Theyhave the additional slldfvety important function of preventing'exposure or spilling oi the consents oi the receptacle in case of the partiel withdrawal-of the in ner receptacle from tlhlehos'ing member as .illnstrnbecl in Fig. s. This partial withy drnwsl may' tene place-'before che handle look. comes; into fiction. A flexible handle le has its ends tucked through slits in the upper well; the receptacle and is there pointed,l riveted or otherwisefsecureel po sition to form s Flexible loop:- Ereferably this handle is eonstructed of' cloth tope' or similar material, thin enough and flexible` ,enough to. offer no substantiel resistanceYA when. the inner receptacle is being slipped linto position within the housing member.

sog

roo

tion, the tongue serves as an effective lock preventing inadvertent sliding motion of the inner receptacle and securely locking the two parts together. Some slight longitudinel movement of the inner receptcle .is

i in

possible as indicated in Fig. 2 but the end extensions 10 and 11 so overlap the face of the inner receptacle Vthat the case still remains intact.

The structure may be reinforced as desired but even in reinforced condition combines great strength and security with lightness, rigidity and freedom from collapse or sagging. l

The cases may be built in any size desired even in sizes small enough for lunch boxes and the like.

What I claim aS new and desire to secure by Letters Patent of the United States is:

1. A knock-down paper box comprising a member having an opening in itsuppermost side, said opening being U-shaped to form a tongue, another portion of said box having a. flexible handle permanently` attached thereto, said flexible handle being adapted for introduction from below so that the handle may be pulledup through. said slot into useful position, said tongue coperating with said handle to prevent accidental withdrawal of the handle throughthe opening.

2. A knock-down case consisting of a housing member open at both ends and havi'nga slot in its top, and a correspondingly shaped inner receptacle adapted to telescope into said housing member through 'an open end thereof, said members being each formed of a single blank alill readilyI flattened out when not in use, said inner receptacle having a flexible handle adapted to project through the slot in said housing member, said hous` .ing member having an integral tongue projecting into said s'lot to serve as a lock for saidI handle.

3. A knock-down paper box consisting of a substantially rectangular housing member, said member being adapted to fold down flat for shipment, a correspondingly shaped inner receptacle adapted to telescope longitudinally lnto said housing member through an open end thereof with a snug fit, said inner receptacle being formed of a single paper blank and capable of ready flattening when not in use, said inner receptacle comnrising a side section, top and bottom sec-.

and a tongue carried by said housing member and projecting into said slot to serve as a stop for limiting accidental endwise movement of said inner receptacle to a distance not exceeding the width of the end extensions. 4. A knock-down case consisting tof a substantially rectangular housing member open at both ends, an inner receptacle adapted to telesco e into Said housing member with a snug fit, said inner receptacle having end extensions overlap inor the front face of said receptacle, a exible handle carried by said inner receptacle, said housing member having an opening through which said handle may protrude, said opening being U- shaped to form a tongue coperating with said handle to preventaccidental displacement of the inner receptacle bv a distance exceeding the Width of said end extensions.

5. A knock-down case consisting of a Substantially rectangular housing member open at both ends, an inner receptacle adapted t0 telescope into said housing member withl a snug fit, said inner receptacle being open along substantially all of one side, a U- shaped slot in said housing member forming a tongue, and a liexible handle carried by said inner receptacle and adapted to pro trude through said slot, said handle coperating with said tongue to form a lock preventing accidental -longitudinal displacement of the inner receptacle.

In Witness whereof, I hereunto subscribe my name to this specification in the presence of two Witnesses. EDWIN BURNHAM STORY.
